| /* |
| * Test Name : sysinfo01 |
| * |
| * Test description |
| * Verify that sysinfo() succeeds to get the system information and fills |
| * the structure passed. |
| * |
| * Expected Result : |
| * sysinfo() returns value 0 on success and the sysinfo structure should |
| * be filled with the system information. |
| * |
| * Algorithm: |
| * Setup : |
| * Setup for signal handling. |
| * Create temporary directory. |
| * Pause for SIGUSR1 if option specified. |
| * Test: |
| * Loop if the proper option is given. |
| * Execute the system call. |
| * Check return code, if system call failed (return=-1) |
| * Log the errno and Issue a FAIL message. |
| * Otherwise, |
| * if we are being called by another sysinfo test. |
| * Print the infomation that was returned for use by the calling |
| * test. |
| * otherwise, |
| * Report success. |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * Delete the temporary directory created. |
| * |
| * USAGE: <for command-line> |
| * sysinfo01 [-c n] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * History |
| * 07/2001 John George |
| * -Ported |

| * Restrictions: |
| * None |
